strip "gecos" information from sendmail.cf

[George A Bodnar]

Trying to figure-out a way using sendmail to replace/remove the gecos part of the "From:" header for JUST a few selected users.

I can find a way to disable this for everyone on the system, but really want to just change for a few batch accounts - I know removing gecos info for the accounts would be easiest - but not the preferred option.

Thanks in advance.
